getting when trying to run the game under Linux
./SGT2_linux: error while loading shared libraries: libSDL2_mixer-2.0.so.0: cannot open shared object file: No such file or directory
Do you have sdl2_mixer installed? You'll need it (and also sdl2_image and sdl2 itself). The name might vary a bit depending on distribution.
Thank you! it works now. so far I'm having a lot of fun with the game!
